World famous resorts MGM has told that last year the information of more than 10.6 million guests have been hacked. All these persons had come to enjoy their time in the resorts.

The news came up when it was first reported by ZDNet that the hacked information has been posted on a hacking forum. The data includes names, addresses and passports of the guests who had come to stay at the resorts.

MGM told that it was not able to identify exactly how many guests personal information has been hacked as it might have been duplicated.

MGM told that it is pretty sure that other more important information like credit card and debit card numbers, passwords has been hacked. Important celebrities like Justin Bieber and Twitter founder Jack Dorsey are among the people affected. MGM had not confirmed this.

MGM confirmed that most of the information that was hacked includes the information from phonebook. So things like telephone numbers, addresses, email address that are publicly available have been compromised.

But on the other hand it has been revealed that more confidential information like passport number had been compromised for nearly 1,300 guests.

Another 52,000 guest’s information that has been hacked does not include passport numbers or other more confidential information.

MGM told that while informing the guests it had followed the laws in the US. According the current laws it is not necessary to inform the customers if any of their public information was expressed to the hackers.

MGM has resorts in three different places in the US- Las Vegas, Atlantic City and Detroit. It also has properties in Asian countries of Chin and Japan. It is also building a resort in Dubai.

Cyber attackers can use different modes to harass using the information that is now under their possession.
